CELL STRUCTURE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
I am a double-membraned cell organelle. I produce energy-rich molecules called ATP. I have my own genetic material. Who am I?
A
Cell membrane
B
Nucleus
C
Plastid
D
Mitochondrion
Explanation: 

Detailed explanation-1: -Mitochondria are double-membraned cell organelles present in the cytoplasm. They have their own genetic material. They produce ATP, which are energy-rich molecules.

Detailed explanation-2: -Mitochondria play host to one of the most important processes in your body, called cellular respiration. Taking in glucose and oxygen, mitochondria produce energy, which they capture and package as energy-rich molecules of ATP.

Detailed explanation-3: -Mitochondria is a cell organelle present in the eukaryotic cells. It is also called as the powerhouse of the cell. It is involved in the respiratory process. It contains enzymes for ATP production.

Detailed explanation-4: -Double membrane-bound organelles: Nucleus, mitochondria and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.

Detailed explanation-5: -Two of these organelles, mitochondria and chloroplasts, play critical roles in energy metabolism. Mitochondria, which are found in almost all eukaryotic cells, are the sites of oxidative metabolism and are thus responsible for generating most of the ATP derived from the breakdown of organic molecules.
